I am having trouble establishing it. I am using Windows XP. I can create the network fine and had another pc join the network but the moment I enable "allow network users to connect through this computers internet connection" under "Internet Connection Sharing" on the host computer it immediately stops data from getting exchanged. It actually cuts my internet right when I enable this even if I haven't connected to the network myself yet. Is there something I'm doing wrong on my end or is this just not possible while using Tether? Thanks for the help.
